THEODORE B. MILLER, OF RICHMOND, INDIANA.

ROLLER WINDOW-SCREEN.

Specification of Letters Patent.

Patented June 26, 1917.

Application filed June 2, 1916. Serial No. 101,393.

To all whom it may concern.-

Be it known that I, THEODORE B. a citizen of the United States, residingin the city of Richmond, in the county of Wayne and State of Indiana,have invented a/new and useful Construction for Roller Window-Screens,of which the following is a full, clear, and comprehensivespecification, being such as Wlll enable others to make and use the samewith exactitude.

The object of my present invention,

broadly speaking, is to provide a roller window-screen which will beneat andattractive in appearance, strong and durable in construction,easily operated and controlled, highly efficient in practice, and

which can be manufactured, sold, and installedat a comparatively lowprice.

More particularly stated, my object is to provide a window screen whichwhen once installed need not be removed, being adapted to roll up out oftheway when so desired, and as easily and quickly brought to operativeposition when required; and having means whereby the screen is at alltimes under tension, by which it will not sag or bulge causing it'to'become inoperative or unsightly.

Other minor objects and particular ad vantages of the invention willsuggest'themselves in the course of the following description and thatwhich is new will be correlated in the appended claims.

One manner for constructing, arranging, and of carrying out my inventionin a practical and mechanical manner is shown in the accompanyingdrawings, in which Figure 1 shows my invention in elevation inconnection with a window, and in closed operative position. Fig. 2 is avertical section of the parts shown in Fig. 1, except that the screen isshown as only partly closed. Fig. 3 is a longitudinal vertical section,taken centrallythrough the roller, showing the screen entirely open,that is wound upon the roller, and showing two springs in theconstruction. Fig. 4: is a longitudinal vertical section taken throughthe roller, the screen being omitted, and showing the construction with,but one spring. Fig. 5 is a plan viewof one of the springs alone. Fig. 6is an enlarged detail of one of the bearings. showing a portion of theroller in position in connection therewith.

Extending Fig.7 is a horizontal cross section as taken through one ofthe vertical guides, as on the line 7-7 of Fig. 2. And Fig. 8 is an endview of the springs.

Similar indices denote like parts throughout the several views. In orderthat the construction, the advantages, and the operation of my inventionmay be fully understood and appreciated I will now take up a detaileddescription thereof in which I will set forth the invention as brieflyand as comprehensively as I may.

In the drawings letters A and B denote the two sides or jambs of awindow frame. C denotes the sill and D denotes the lintel. It will beunderstood that the window frame may be fitted with the usual sash orsashes, and that it may be of any desired form, the particular style orshape shown being simply for convenience of description, but theinvention is not to be limited thereto.

The invention proper comprises the two end plates, 1 and 2, which areadapted to be secured to the opposing faces of the re spective jambs Aand B, by nails or screws.

Permanently connecting the plates 1 and 2, and extending th'erebetween,is the hood or container 5, which is tubular in shape, but with alongitudinal slot extending from end to end thereof, which slot opensdownward and to one side, as indicated at w in Fig. 2, to form themouth. One lip of the mouth extends down vertically a short distance, asindicated at vin Fig. 2.

Secured to and projecting inward from.

the respective plates 1 and 2 are the tubular bearings 6 and 7, whichare concentric with the hood 5, and project thereinto a short distance.

Numeral 8 denotes the tubular roller which extends across with its endsfitting either around orwithin the said bearings, on which bearing theroller is adapted to revolve, as hereinafter set forth.

Located in the end portions of the roller 8, parallel therewith, are thehelical springs 9 and 10. The end portions of said springs are doubledback diametrically across the ends of the springs to form slotted eyes aat each end of each spring, the termini being secured by twists aroundthe end of the last coil at each end of each spring, as shown in Fig.

through the roller 8, and

through the inner eye of the springs are the respective pins 11 and 12,by which the springs are connected to the roller 8.

Likewise extending across through each of the bearings, 6 and 7, are therespective outer pins 13 and 14 which pass through the outer slots inthe eye terminals of the respective springs 9 and 10, by which the outerends of the springs are connected to the bearings and are, therefore,stationary with relation to the inner ends of the springs, which latterrevolve with the roller.

Numeral 15 denotes a wire screen, whose width is slightly less than thedistance between the jambs A and B, and whose length is such as to coverthe interior space of the window frame. The upper edge of the screen issecured along on the periphery of the roller and parallel therewith.

Secured to the lower edge of the screen is the angle-strip 16, whosebase is adapted to contact with the sill C, and whose length issubstantially the same as the width of the screen.

Secured to the respective jambs A and B are the guides 17 and 18, eachcomprising a single length of sheet metal having a base portion adaptedto be secured to the jambs by screws or nails, from which base portionthe metal extends inward and is reversed outwardly with the two portionsin contact with each other, and then projecting outward and spaced fromthe double portion to form the channels, as indicated at f in Fig. 7, inwhich channels may operate the end of the strip 16 and the edges of thescreen, as shown.

Formed horizontally through the end portions of the strip 16 are smallapertures which register with like aperatures 12 formed through theprojecting flanges of the guides, to receive the removable pins 19 and20 by which the screen may be secured either in closed position or atvarious points in partly open position as desired.

Extending out and upward from .the angle strip 16, and located near theguides 17 and 18, are the hooks 21 and 22, which are adapted to engagewith the lower edge of the lip a when the screen is rolled up, therebynot only limiting the upward movement of the screen but also centeringthe screen in its movement in the guideways 17 and 18.

From the above it Will be noted that the entire mechanism may beassembled in operative position, except the guides, before being securedin the window, the only labor required being to insert the device inplace and secure the plates 1 and 2 and the guides 17 and 18 to thewindow jambs, it of course being understood that it has been prepared toexactly fitbetween the jambs.

When the device is being assembled the springs are placed under propertension, such as to normally retain the screen wound Fig. 4, while forother end of the screen, means upon the roller to its limit. After beingplaced in position it is apparent that one may grasp the base portion ofthe anglestrip 16 and by pulling down the screen will unroll, the rollerrevolving against the tension of the spring or springs, and when broughtdown, as in Fig. 1, the pins 19 and 20 can be inserted, which willretain the screen in closed position as shown.

In connection with ordinary or small windows only one spring will berequired, this being placed at one end of the roller, as in largerwindows it is best that two springs be employed, as indicated in Fig. 3.Also the length of the springs will depend somewhat on the length of thescreen in connection therewith.

Screens thus arranged need not be removed during the months they are notrequired, but they may be simply released, by removing the pins 19 and20, and allowed to roll up out of the way where they will be protectedand be in readiness when again required.

I desire that it be understood that various changes may be made in theseveral details of construction herein set forth without departing fromthe spirit of my invention and without sacrificing any of the advantagesthereof.

Having now fully shown and described my invention, what I claim anddesire to secure by Letters Patent of the United States, 1S-

1. A roller window screen comprising end plates attached to the windowjambs. bearings projecting toward each other from said plates, a rollermounted in connection with said bearings, a screen having one endattachedto the roller and adapted to be wound therearound, a metal stripsecured to the for automatically causing the screen to be wound upon theroller, a hood surrounding the roller and the screen, there being adownwardly opening slot through said hood for the screen to operatethrough, hooks carried by said strip and adapted to engage one of thelips of said slot. and guide-ways secured to the window jambs andextending downward in alinement with said slot.

A roller window screen adapted to roll upward and to be unrolled whenthe free strip secured along the free end oi the screen, hooks carriedby said strip for securing said strip upon the window sill; a. hoodsurrounding the roller and adapted to inclose the screen when the screenis wound upon the roller, there being a downwardly opening slot in thehood for the screen to operate through and through which slot the saidhooks can not pass, guide-ways secured to the window jambs and extendingdownwardly from said slot to the Window sill with the edges of thescreen adapted to operate in said guide-Ways, all substantially as shownand described.

In testimony whereof I have hereunto 15 subscribed my name in thepresence of two subscribing witnesses.
